實驗八直流電機開環(huán)控制實驗

實驗八直流電機開環(huán)控制實驗提高部分：1、在分析掌握基于SST89E554RC微控制器實現(xiàn)直流電機控制電路原理基礎上，實現(xiàn)電機速度可調；本程序利用ADC0808采樣來改變PWM波，從而實現(xiàn)電機的無極調速。【電路原理圖protues】LUEUEUEUELUELUEUEU2(CLOCK)—LED-BLUEk‘XTAL1182030-3^12345678XTAL2RSTPSENATEEAP1.0P1.1P1.2P1.3P1.4P1.5P1.6P0.0/AD0P0.1/AD1P0.2/AD2P0.3/AD3P0.4/AD4P0.5/AD5P0.6/AD6P0.7/AD7P2.0/A8P2.1/A9P2.2/A10P2.3/A11P2.4/A12P2.5/A13P2.6/A14P2.7/A15P3.0LUEUEUEUELUELUEUEU2(CLOCK)—LED-BLUEk‘XTAL1182030-3^12345678XTAL2RSTPSENATEEAP1.0P1.1P1.2P1.3P1.4P1.5P1.6P0.0/AD0P0.1/AD1P0.2/AD2P0.3/AD3P0.4/AD4P0.5/AD5P0.6/AD6P0.7/AD7P2.0/A8P2.1/A9P2.2/A10P2.3/A11P2.4/A12P2.5/A13P2.6/A14P2.7/A15P3.0/RXDP3.1/TXDP3.2/INT0P3.3/INT1P3.4/T0P3.5/T1P3.6/WR383736353433322
